This custom connector is a double-row, 14-pin, extended (22.85 mm) male header strip. This connector is included with the 3pi expansion kits (MCM Part# 28-17629) for connecting the expansion PCB to the 3pi robot (MCM Part# 28-17626).

This connector is a double-row, 14-pin, extended male header strip. The extra-long pins have a length of 22.85 mm, which is 11.2 mm longer than typical 0.1" straight male header pins. The standard 0.1" spacing allows use with perforated prototyping PCBs and female headers.

This connector was specifically designed for routing electrical connections from the 3pi robot (MCM Part# 28-17626) base to an expansion board. It is provided as part of the 3pi expansion kits (MCM Part# 28-17629), including the PCB-less hardware-only kit (MCM Part# 28-17633).

A two-pin version of this extended header is also available (MCM Part# 28-17709), as is a shorter version (MCM Part# 28-17710).
